I. Split Window Into 4 Parts
-This will allow you to see your project from multiple angles at once (making it much easier to edit)

The screen split into four parts

-Right-click on the line where the buttons window meets the project window, then click "Split Areas"
-Move the line into the middle of the screen and click to split it
-Do this twice more on the new line to create 2 horizontal lines on the left and right sides (4 windows total)
-Set each to a different view (front, side, camera, top)

II. Building a Roof
-With the default cube highlighted, hold Shift and press D (Duplicate) to make a copy of it
-Hold Ctrl while grabbing (G) the new cube to "Snap to Grid," making it easier to place it directly on top of the first cube
-Go into Edit mode, then press B and click and drag a box around the top four vertices of the roof

Making a roof in Edit mode

-Press S for scaling, limit it to the X-axis with the X key, then press 0 to bring the shape to a point
-Back in Object mode, use S to resize the roof so that it is slighly bigger than the main house
-For a chimney, simply resize a cube mesh in edit mode and attach it to the roof part
-You can also rename each part by selecting it and going to where it says "ME:Cube" and "OB:Cube" under "Link and Materials," changing "Cube" to "House," "Roof," or "Chimney"

III. Coloring
-Select the part you want colored and click on the red circle icon in the buttons window
